LOCOMOTIVE-HEADLIGHT.

Specification of Letters Patent.

make and use the same.

My invention relates to locomotive-head- I lights and means for automatically adjusting the same to cause the lights to illuminate the track when rounding a curve; and it consists in the construction,Il combination, and arrangement of devices hereinafter described anl claimed.

n the accompan bng-drawin s, Fi ure 1 is a side elevation ofY1 a locomotiie-hedlightadjusting means embodying my invention,

and Fig. 2 is a perspective view of the same with parts broken away.

be of the usual orv of of the headlight is pivotally mounted, as at 2, in a frame 3, wiich frame may be supported at the front end of the locomotiveoiler by means of supporting-brackets such as are ordinarily employed. The headlight is provided at its upper end with a pivot 4, which is in line with the pivot 2 and has its bearing in the frame 3. A bar 5 is rigidly secured on the upper side of the headlight 1 and turns therewith. In the rear side of the frame 3 is a pendulum-.bar 6, which is fulcrumed at 7 and is provided at its lower end with a cross-bar 8, to which is secured a weight 9. A bar 10 is pivotally mounted, as at 11, under the t `of the frame 3 and is provided with a rearwardly-extending arm 12, the rear end of which is notched, as at 13, to receive the upper end of the pendulumbar 6 and provides a loose pivotal connection between said pendulum-bar and the bar 10. The ends of the latter are connected to the ends of the bar 5 by links 14, which are pivotally connected to said bar 1Q and bar 5 as at 15 16.

When a locomotive which carries the headlight is-traveling on a straight track, the pendulum-bar will remain in a vertical position' and will hold the headlight against ivotal movement so as to direct the rays of ight from the headlight directly along'the track. When the locomotive reaches a curve and becomes slightly tilted by the ra :Sed outer rail of the curve, the pendulumbar in order to keep in a vertical position will describe angular movement with reference to the frame 2, and such angular' movement of the pendulum-bar will cause the har 10 to `slightly turn and the headlight to turn therewith in the direction re uired to illuminate the curve ahead of the ocomotive, -as will beunderstood.

From the foregoing description, taken, in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

.Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages 'y i of this invention as defined by the appended claim. l

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In combination with a supporting-frame, a locomotive-headlight in the front side thereof partially incased thereby and having pivots at its upper and lower ends in bearings in the upper and lower sides of the frame and pivotally mounting said headlight for horizontal angular movement in the front portion of the frame, a pendulum-bar pivotally mounted in the rear' side. of said frame and having a weight at its lower end, a bar pivotally mounted under the upper side of said frame and having a rearwardly-extending frame connected to the upper end of said pendulum-bar for angular movement with reference thereto, and link-bars, each having its front end pivotally connected to the upper side of the headlight and its rear end pivotally connected to one end of said pivotally- -mounted bar.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
